Description

  The present invention relates to a method for integrating the components of a smoking article and to machines of the tobacco processing industry, in particular filter mounting machines. Furthermore, the invention relates to a multifunctional drum as well as a transport drum for articles of the tobacco processing industry.

  In the filter mounting machine, one filter element or mouth element is applied between the cut and longitudinally-spaced tobacco rods, and one glued sheet is subsequently attached to the tobacco mouth element. Pasted to the group. In this case, the glued sheets are fed via a suction roller of one of the backing means at defined intervals of the group of tobacco spout members. A defined dividing interval is in this case understood in particular as a dividing interval determined by the length of the binding paper.

  A method and apparatus of the kind described above serve for the mass production of filter tobacco conveyed transversely to so-called filter mounting machines. The output for articles produced and released per unit of time is gradually increased again and again, or the increased performance must be adapted to a previously connected tobacco strand former.

  A document, DE 3918137 [consistent with U.S. Pat. No. 5,054,348] describes a backing paper aggregate in a filter mounting machine. In this case, the glued backing paper is supplied as an endless backing strip and cut into individual sheets or combined sheets by one cutting device. After cutting, the combined sheets are separated and brought to the transport speed of the tobacco filter tobacco group transported in small quantities.

  At this time, the endless backing paper strip is conveyed at a constant paper traveling speed to a glue application point in a region in front of the glue device. In the area between the glue application point and the suction roller for the cut bonded sheet, the paper running length in the production process is not reduced. The backing sheet that is currently produced after cutting and singulation (disassembly) is held by a suction roller and transported at a uniform speed, which is higher than the paper running speed of the endless backing strip. At this time, the peripheral speed of the suction roller corresponds to the speed of the tobacco filter rod tobacco group transported little by little.

  The paper running length in the area between glue application and cutting on the suction roller is continuously reduced during the knife action, so that a separation occurs before the suction roller in the paper running. Even though the transport speed of the endless paper band is lower than the outflow speed of the suction roller, sufficient paper length is always free, so that the paper is not moved with respect to the roller during knife action. , More economical cutting is possible. After cutting, the paper is returned to the roller through the length of the paper path between the glue application point and the suction roller, and on average, the paper traveling speed is lower than the peripheral speed of the suction roller. Achieved in line with the speed of the tobacco produced. Thus, the paper running speed is always fluctuated by an average value, the amplitude of this speed fluctuation being directly related to the length of the individual sheets and the spacing of the tobacco articles conveyed in small quantities.

  Since the paper running length between the glue device and the suction roller is periodically changed in order to generate the paper running speed fluctuation, the tension fluctuation in the paper running and the return action to the glue application process occur. . Above a certain amplitude, this method reaches the limits imposed by the tensile strength of the backing material and the glue application by adapting the paper running speed in order to speed adapt the paper running and tobacco articles.

  DE-A-196 26 679 describes a filter mounting machine for a double-strand tobacco production machine, in which two different transport paths for tobacco articles are provided with a backing paper band. It is provided for attaching and winding.

It is known from EP-A-108 369 to provide a cigarette filter tobacco group with a backing sheet, in which each first group of successive cigarette filter tobacco groups has a first drum. A backing sheet of the first backing means, wherein each second group is conveyed to the outside from the conveying path of the first group, and provided on the second drum with a backing sheet of the second backing means. I have. The winding of the two individual groups by the sheet is likewise effected by separate winding means. Only after each winding the groups are again assembled into one alternating continuous group.
German Patent No. 3918137 [US Pat. No. 5,054,348] DE-A-196 26 679 EP 108369 A1

  Starting from this state of the art, it is an object of the invention to provide that the high production quality of smoking articles is assured at higher production output with a filter mounting machine, while the costs for the construction are kept as low as possible. I do.

  The object is to provide a first and a second group of articles comprising a tobacco mouth member tobacco group, each provided to one backing means, each comprising one binding sheet, and a first and a second group of articles. Is delivered to one common wrapping means, wherein the first and second groups of articles integrate the smoking article components that are wrapped around the wrapping means by the binding paper.

  With the method according to the invention, it is possible to operate the one-way filter mounting machine at a high production speed, since the backing paper supply is formed twice for the articles, so that one half of the articles This is because the (first group) is provided with the combined paper sheets by one backing means and the other half (the second group) by the other backing means. In addition, a simpler construction known from the state of the art by a subsequent one-way winding of the article, while at the same time a compact construction is possible. In addition, costs are saved by scheduling only one winding means.

  To that end, the first and second groups of articles are first supplied to the first backing means, the first group of articles being provided with the binding sheets by the first backing means, and then the first and second articles. The two groups of articles may be delivered to different transport paths of the common wrapping means, and the second group of articles may be fed to that transport path of the second backing means, each having one binding sheet. Is provided.

  In particular, the transport speed of the first and / or second group of articles can be varied before and / or after the transition point of the respective binding sheet. The adaptation of the speed relationship between the conveyed articles and the backing paper supply is thus possible by targeted control of the speed of the tobacco articles. The adaptation takes place before, during and after the application of the binding sheet and is independent of the speed in the remaining production stream and the speed of the paper running in the filter setting machine. During the speed change, the tobacco articles are moved individually, in pairs or in any number of times. At that time, not only the speed but also the interval between the tobacco articles is changed.

  In one embodiment, the first and / or the second group of articles are braked before the transfer of the combined sheets.

  Furthermore, the articles of the first and / or second group are accelerated after the transfer of the binding sheet.

  Speed change refers to a decrease or increase in the speed of the tobacco article being conveyed relative to the output speed or average conveying speed. The functional separation of speed changes in paper running is important for the transport speed and the spacing of the tobacco articles to be adhered with the backing paper. The consistency of the transport speeds of the paper and tobacco articles need to be considered only locally and temporally only for the process of applying the backing sheet to the first and / or second group of articles. Thereby, the speed relationship in the backing paper supply is matched with the speed in the conveyance of the tobacco article to be stuck.

  In addition, it is possible to reduce the distance between tobacco articles to be conveyed during the application process due to speed fluctuations, thereby stabilizing the production process. At the same time, the spacing required to separate the backing sheets is minimized, and speed changes caused by paper return (by vibrating the backing device) are reduced in the paper run. This causes a slight tension fluctuation in the paper running between the glue application site and the cutting of the backing strip. Overall a better glue application, a more precise glue image, less smearing, less chance of tearing and better cutting results. Thereby, the invention guarantees a reliable and stable production at the same low sensitivity of the process in the variation of the properties of the production material.

  Another improvement is achieved by the binding sheet being partially applied to the first and / or second group of articles after transfer. The application of one free end of the binding sheet to the tobacco filter rod tobacco group is described in European Patent Application No. 0 202 2354.8, the contents of which are fully contained in this patent application. A folding star or a so-called roller star is provided to apply one free end of one binding sheet to one tobacco article.

  In one embodiment, the second group of articles is removed by a common transport drum for the first and second groups of articles. In this case, the first and second groups of articles are supplied to the first group backing device before the removal of the second group of articles.

  In particular, the articles of the first and second groups are alternately arranged on one transport drum before the transfer of the combined sheets to the first group.

  Furthermore, the articles are supplied to a common winding means, preferably because the articles of the first and second groups are alternately arranged on one transport drum during the assembly of the article groups.

In particular, the bonded sheets are transferred at a constant speed to the first and / or second group of articles.
[Second means for solving the problem]

  The object is further to provide a machine for the tobacco processing industry which reproduces that one backing means and one common wrapping means are respectively provided for the articles of the first and second groups of the tobacco mouth member tobacco group. , Especially with a filter mounting machine.

  In order to match the speed relationship between the backing means and the transport drum, at least one transport drum is provided for the process of backing the articles by one combined sheet, and the first and / or second group of articles is provided. It is provided that the space between the parts can be changed.

  In order to change the partial spacing for the articles, the transport drum is preferably formed as an arm drum. In this case, the transport drum has an arm, a lever, and the like, and the partial interval thereof can be changed in the transport direction, so that the transported article is accelerated with respect to the (average) transport speed of one transport drum. Or braking.

  In one alternative embodiment, the transport drum is provided with a particularly pivotable lever segment. The lever segment is particularly pivotally arranged on one drum body, and the articles conveyed by the rotation of the lever segment during rotation of the transport drum are accelerated in relation to the rotation speed of the transport drum, or Be braked.

  In addition, it is advantageous when the first and / or second group of articles is provided with at least one free-end abutment of a sheet, so that the part of the partially connected components on one transport drum The spacing is reduced and the backing sheet is applied better in the next wrap around the article group.

  In a preferred arrangement, one multifunctional drum is provided for the first and second groups of articles.

In particular, the multifunctional drum is formed in such a way that at least one free end of the backing sheet is applied to a group of articles and another group of articles is removed from one transport drum. In this case, the multifunctional transport drum integrates the functions of one contact member and the take-out drum. The implementation of both functions, which can be performed simultaneously, reduces the production sequence on the machine. In addition, costs are saved because only one working member is required instead of two working members.
[Third means for solving the problem]

The object of the invention is further solved by said multifunctional drum for articles of the tobacco processing industry.
[Fourth means for solving the problem]

  In addition, the object of the invention is solved by a transport drum for articles of the tobacco processing industry, which is reproduced by the provision of a pivotable lever segment for the articles. Since the partial spacing between articles or article groups can be changed by the lever segment, the articles on one transport drum are accelerated or braked. In order to avoid repetition, it is indicated to explicitly refer to the implementation for the lever segment.

  Further, since the lever segment has a container for articles, the articles can be gently conveyed to one filter mounting machine.

  Furthermore, it is advantageous if the distance between the two containers on one lever segment is greater than the free end of one sheet between the articles.

  In particular, at least one spacing member is provided in the lever segment for retaining one free end of the backing sheet.

  The present invention will now be described, by way of example, with reference to the drawings in which all details of the invention that are not otherwise described in detail herein are set forth without limitation of the general inventive concept. It is described in.

  In the drawings, similar or similar elements and / or components have been provided with the same reference signs, and new introductions have been omitted.

  In FIG. 1, one filter installation machine is shown in cross section in a front view, and the filter installation machine is provided with one cigarette not shown here via one drum arrangement T for supplying tobacco rods. Receiving double use length tobacco sticks by strand forming machine. The tobacco rod is cut and spread on the transport path of the tobacco rod relative to the knitting drum 21. A double-length filter element is conveyed on the knitting drum 21 via one other drum arrangement M, each of which is fitted between two longitudinally spaced tobacco rods. As a result, on the knitting drum 21, a group of tobacco port member cigarettes arranged one after another in a continuous horizontal axis direction is formed.

  The knitted articles 50 and 60 (see FIG. 2 or FIG. 3) on the knitting drum 21 are transferred to the transport drum 22 and transported to one backing device 10.1 for the first group 50. U.S. Pat. No. 5,077,077 clearly describes a backing device, the entire scope of which is covered by the content of this application.

  The glue-fed backing paper strip is cut on one cutting drum 12.1 by a knife of a knife drum 13.1 into a backing paper leaf 40.1 (see FIGS. 2 and 3). The cut backing sheet 40.1 is transferred to the first group of articles 50 on the transport drum 22.

  Subsequently, the articles 50, 60 (see FIG. 2) are further transported to the backing star 23.1, which has the front end of the backing sheet 40.1 applied to the article 50. Next, the articles 50 and 60 are further conveyed and supplied to one take-out drum 24, and the take-out drum 24 takes out the second group of articles 60 from the drum 22 having no combined sheet.

  The take-out drum 24 transfers the removed articles 60 of the second group to the transport drum 25, which transports the articles 60 of the second group to one backing device 10.2 (see FIG. 2). ). The second backing device 10.2 has a knife roller 13.2 that cooperates with the suction roller 12.2. The cut combined paper sheet is transferred to the tobacco article or the tobacco mouth member tobacco group 60 and is attached. Thereafter, the leading edge of the combined sheet is applied to the article 60 on the transport drum 25 by the folding star 23.2. The transport drum 25 supplies the second group of articles 60 to one drum 26.

  Since the transport drum 26 simultaneously receives the articles 60 further transported on the first group of transport drums 22, the articles of the first group 50 and the second group 60 are alternately arranged on the drum 26. Next, the articles of the first and second groups 50,60 are conveyed to the winding means 27 having a roller log, so that the combined sheet is completely wrapped around the tobacco mouth member tobacco groups 50,60. . The successfully wound articles 50,60 are then transferred to one transport drum 28 and one other transport drum 29 and are prepared in one filter mounting machine for further processing.

  FIG. 2 schematically shows in detail a detailed view of the removal of the articles of the first and second groups 50, 60 of the tobacco spout member group from the knitting drum 21 and transporting them to the drum 24.

  The articles 50 and 60 are transferred from the knitting drum 21 to the transport drum 22. Since the transport drum 22 has a movable arm having a container for the articles 50 and 60, the interval between the articles 50 and 60 arranged alternately can be changed. Speed adaptation occurs at the speed of the suction roller 12.1. This is because the matched articles 50, 60 are decelerated before the transition of the combined sheet 40.1 to the articles 50, 60 at the transition point of the combined sheet 40. 1 to the articles 50, 60. 1 and each article 50 have the same speed. After the transfer of the binding sheet 40.1, the articles 50, 60 are accelerated on the transport drum 22. Subsequently, the leading edge of the sheet 40.1 bound to the article 50 is applied to the article 50 by the folding star 23.1. While the articles 50 are conveyed to the drum 26 (FIG. 1) together with the binding sheets 40.1 on the drum 22, the articles of the second group 60 that do not yet have the binding sheets are removed from the unloading drum 24 by one. It is supplied to the transport drum 25 (FIG. 1).

  Although the braking acceleration process is carried out substantially in the area of the transition point of the combined sheet 40.1 to the article 50 independently of the transport speed of the drum 22, the accommodation of the articles 50, 60 in order to adapt the speed is carried out. Alternatively, it is carried out when the backing sheet 40.1 is applied to the transfer and the article group.

  In an embodiment not shown here, the arms are formed such that a plurality of articles 50, 60 are received by one arm segment. In particular, one article of the first group and one article of the second group 60 are arranged in a container on each of the arm segments. The spacing of the containers is such that the free end of the combined sheet between the articles 50, 60 does not come into contact with each of the preceding or tracked articles when attaching the backing sheet 40.1 to the articles of the first group 50. Is formed.

  By changing the spacing between the articles of the first group 50 and the articles of the second group 60, a sufficient spacing has been created outside of them, so that the combined sheet 40.1 comes into contact with the articles of the other group 60. Without doing so, the bonded sheet 40.1 is applied to the article 50 from the first backing device 10.1.

  FIG. 3 shows an alternative embodiment in which the application of the front end of the binding sheet 40.1 to the article 50 is effected by one patch 33, which comprises the binding leaf. It is formed so that the unremoved articles 60 can be taken out at the same time. Thus, the contact member 33 integrates the functions of the folding star 23.1 and the take-out drum 24 from FIG. Since the lever segments 35 or 36 are provided on the transport drum 22 or 25 in order to adapt the speed of the articles 50 and 60 to the transport speed of the combined paper sheets 40.1 and 40.2, the lever The speed of the articles 50, 60 conveyed by the turning of the segment 35 or 36 is reduced before the transition point of each combined sheet 40.1, 40.2 to the articles 50, 60, so that the combined sheets 40.1, 40.1, It is accelerated after the transition of 40.2. For this purpose, the drums 22, 25 have the same function.

  The lever segment 35 of the transport drum 22 has one compartment for the article group 50 and one compartment for the article group 60 for each of the two article groups 50, 60. The distance between the storage containers on the lever segment 35 is determined such that the trailing end of the combined sheet 40.1 does not contact the rear article group 60 after the contact of the combined sheet 40.1. On the other hand, the lever segment 36 of the transport drum 25 has only one storage section for the article group 60, because the articles 60 which are not yet provided with the combined paper sheet through the transport path for the article group 60 are the This is because it is supplied to the double backing device 10.2 (see FIG. 1). The lever segments 35 and 36 are arranged so as to be pivotable on one partial circle of the transport drums 22 and 25 and have a shape that tapers down to the inside of the drum. In addition, since the lever segments 35, 36 have barbed spacing members 39, the placement of the combined sheets 40.1, 40.2 on the lever segments is prevented.

  4a and 4b, the cross section of the lever segment 35 of the transport drum 22 is shown in a front view or a cross section. The lever segment 35 is formed with two receiving portions for the articles 50 and 60 to be received by the knitting drum 21. The lever segment 35 can pivot about a pivot axis 37 that is aligned parallel to the axis of rotation of the drum 22. The pivoting of the lever segment 35 during the rotation of the drum 22 is effected by one guide transmission 38 (FIG. 4b), in which one curved disc is guided to the machine side by one curved track. The lever segments 36 of the drum 25 are formed analogously and with the same function, and the receiving section is provided only for the article group 60.

  Each lever segment 35 has one container for the articles of the first group 50 and the articles of the second group 60 respectively. A spacing member 39 is provided between the accommodating portions, and the spacing member avoids placing the combined sheet on the lever segment after applying the combined sheet 40.1 to the articles of the first group 50. I do. The distance between the storage containers is determined so that the trailing edge of the combined paper sheet 40.1 does not contact the rear article group 60.

  Furthermore, in an embodiment not shown here, the articles 50, 60 on the drum 22 are arranged on a lever which is movable or movable radially and / or tangentially.

  The object of the invention makes it possible to increase the filter mounting speed of the filter mounting machine even with high format flexibility, in that the backing paper for the tobacco articles to be wound is supplied in a bi-orbital manner. A group of cigarette filters with cigarettes is wound around one winding means in one orbit.
